Modelling of the Knitting Process during the Knitting-in of Elastomeric Threads Using Knitting Machines with Relanit and Classic Knitting Zone

An analysis of the knitting process during the knitting-in of elastomeric threads using knitting machines with a Relanit and classic knitting zone was made on the basis of simulations considering a numerical model which takes into account the most important parameters of the knitting process, viscoelastic properties of the thread and geometrical parameters of the knitting zone. The conditions of forming stitches from classic cotton yarn were presented for comparison. The results of the simulation tests were verified experimen-tally on a computer-aided knitting machine with a classic knitting zone. Key words: elastomeric threads, knitting zone, Relanit technique, modelling of knitting pro-cess, forces in threads, thread length in stitch. β ‑ angle of lifting the needles, in °, βp- angle of lifting the sinkers in Relanit technique, in °, Ri- curvature radius of cams in the knit-ting zone for needles, in mm
